1.1. About Red Hat Developer Toolset
Red Hat Developer Toolset is a Red Hat offering for developers on the Red Hat Enterprise Linux
platform, and provides a complete set of development and performance analysis tools that can be
installed and used on multiple versions of Red Hat Enterprise Linux. Executables built with the Red Hat
Developer Toolset toolchain can then also be deployed and run on multiple versions of Red Hat
Enterprise Linux. For detailed compatibility information, refer to Section 1.3, “Compatibility”.
Critically, Red Hat Developer Toolset does not replace the default system tools provided with Red Hat
Enterprise Linux 5 or 6 when installed on those platforms. Instead, a parallel set of developer tools
provides an alternative, newer version of those tools for optional use by developers. The default
compiler and debugger, for example, remain those provided by the base Red Hat Enterprise Linux
system.
Red Hat Developer Toolset differs from “Technology Preview” compiler releases previously supplied in
Red Hat Enterprise Linux in two important respects:
Red Hat Developer Toolset can be used on multiple major and minor releases of Red Hat Enterprise
Linux, as detailed in Section 1.3, “Compatibility”.
Unlike Technology Preview compilers and other tools shipped in earlier Red Hat Enterprise Linux,
Red Hat Developer Toolset is fully supported under Red Hat Enterprise Linux Subscription Level
Agreements, is functionally complete, and is intended for production use.
Important bug fixes and security errata will be issued to Red Hat Developer Toolset subscribers in a
similar manner to Red Hat Enterprise Linux for two years from the release of each major version release.
New major versions of Red Hat Developer Toolset will be released annually, providing significant
updates for existing components and adding major new components. A single minor release, issued six
months after each new major version release, will provide a smaller update of bug fixes, security errata,
and new minor components.
Additionally, the Red Hat Enterprise Linux Application Compatibility Specification also applies to Red Hat
Developer Toolset (subject to some constraints on the use of newer C++11 language features, detailed
in Section A.1.3, “ABI Compatibility”).
Important
Applications and libraries provided by Red Hat Developer Toolset do not replace the Red Hat
Enterprise Linux system versions, nor are they used in preference to the system versions. Using
a framework called Software Collections, an additional set of developer tools is installed into
the /opt directory and is explicitly enabled by the user on demand using the supplied scl utility.
